Go visit Doc Whites web site, he has some loads listed for the White Tominator that use as little as 1 1/4 oz of shot. http://www.whitemuzzleloading.com/images/whiterifles/Tominator.htmthere are also some lighter loads for smaller foul hunting that could work for turkey too. The Knight you have is not much different from the White Tominator and load information should be interchangable. Be warned, working up a load can be time consuming with all of the varriables involved with shotgun components. Have fun.

Oh, my present load consists of a BP Multi-Metal 12 gauge 3.5" long cup, 2.25 oz copper plated #5 shot and 80-90 grains of Goex Pinacel powder, 80 grains ofTriple 7 workswell too. I don't use an over powder wad but do use an over shot wad, I make my own over shot wads out of pink or blued foam construction insulation board I find on job sites, use an IP choke to cut out plugs of foam then slice them into 1/4' thick disks. I use 2 of the foam disks on top of the shot to hold it in place. And the choke is .665" constriction.
